Application filed March 18, 1920. Serial No. 366,755.

To all whom it mayconaem:

Be it known that I, AUGUs'r F. HABE- NIGHT, a citizen of the United States, residing at Tinley Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Acetylene- Gas and Pressure Generators, of which the following is a specification.

This invention relates to gas generators of that class employed in the generation of acetylene from calcium carbid, and has particular relation to that kind of such generators in which the carbid is supplied to or fed into water or decomposing liquid therefor instead of the water being supplied to the carbid, and it consists in certain peculiarities of the construction, novel arrangement, combination and operation of the various parts thereof as will be herein after more fully set forth and specifically claimed.

The principal object of-the invention is to furnish a gas generator of the above mentioned general charactenwhich shall be simple and inexpensive in construction, strong, durable, safe and efli'cient in operation, and

.which'is more particularly intended for use in shop work for welding purposes, yet may be used for the generation and supply of gas for illuminating or heating purposes.

Another object is to provide a gas generator which shall be automatic inits operation, after being charged or loaded with suitable supplies of water and carbid.

Various other objects and advantages of theinvention will be disclosed in the following description and explanation.

In the accompanying drawings, which serve to illustrate an embodiment of the invention- Figure 1 is a general view mainly in elevation and partly in section of a gas generator embodying my invention.

sponding parts throughout the different views of the drawings.

The reference numeral 7 designates the combined generator tank and gasometer,

which may be made of any suitable size,

of the tank 7 when it is desired to clean the same.

The tube or member 9 has on opposite sides thereof spaced apart lugs 10 between eachpair of which is pivota ly mounted a screw-threaded bolt 11 which bolts are adapted to enter diametrically opposed slots 12 in a head or cap 13 used for closing the outlet 9 or said tube.

The head or cap 10 is held in place by means of wing nuts 14 engaging the screw bolts 11, and it is obvious that the cap may be removed from the outlet'9 by disengaging said nuts'from the bolts on which they are mounted.

Theupper end of the tank 7 is provided with an inlet 15 which is equipped with a closure of similar construction and arrangement to that just above described in connection with the outlet 9 or discharging tube. r

The tank 7 is mounted on the support 8 so that its outlet 9 will extend downwardly through an opening therein, and by reference to Figs. 1, 3 and 4 of the drawings, it will be seenthat the top of said tank is provided with a pressure indicator 16 of the ordinary or any well known construction used for the purpose of indicating the pressure contained in the tank. Closely secured to the lower surface of the top of the tank 7 by means of screw bolts 17 or otherwise is .an annular flange 18 on the upper end ofthe carbid receptacle 19 which may form and material. The flange 18 of this receptacle surrounds the inlet 15 so that the carbid can be readily placed in its container. Located horizontally and a slight distance below the container 19 is a shelf or platform 20 which is supported by means of brackets 21 secured to the edges thereof and to the sides of the carbid container as will be readily understood by reference to Figs. 3 and 5 0f the drawings.

7 surface of thedoor and As shown in Fig. 3'the shelf or platform 20 has at one of its ends an angular extension 22 the vertical wall 23 of which is located inwardly from the front wall of the container 19, whileitsfloor 24'eXtends hori-j forwardly of said wall. The V front walliof the zontally and container 19 is provided with a doorway 7 p which is closed by a'door 26 secured by means of hinges '27 at its upper endto the carbid container. 7 This door' is normally held closed by means of a spring 28 which is securedat one of its ends to the inner at its other end to the rear wall of the container 19. Slidably located on the upper surface of the platform20. is a car-bid feeding member which consists of a flat plate 29 havingat its front enda downwardly extended flange 30 which coincides with p v the vertical portion 23 of the extension 22 of the shelf or platform 20. Transverscly journaled in suitable hanger's on the lower surface of the platform 20 is a horizontally disposed shaft 32, which as shown in 'Figs. land 3, extends through the wall jof the tank 7. This shaft is provided at a point about the middle of the platform 20 with an'upwardly extended crank arm 33 whichprojects througha slot 34 in the platform and engages an opening 35 in t the feeding slide 29 so that when the shaft '32is-rocked, said slide will be movedback and forth to the end that, the flange 30 on the slide will force off the quantity o'f'carbid held on the floor 24of the extension 22 of the platform 20 and allow it to drop into the water 36 contained in the lower portion of the generating tank as will be readily understoodby reference to dotted lines in Fig. 3 ofthe drawings. I

In the above stated operation, it will be understood that the door 26 will be moved forwardly to about the position shown by dotted lines in Fig 3, in the forward movement of the feeding slide 29 and its flange 30 by reason ofthe [carbid interposed between the door and said flange. In the return movement of the slide 29 the. spring 28 will retract or close the door 26 as is ob- Vious.

The bearing injthe wall of the tank j for theshaft 32 is provided with a suitable .packing 37 and a gland 38 to hold said packing in place so. as to'prevent the escape ofgas. vBigidlysecured to the outer portion of thefshaft '32 is a crank arm 39 which is .pivotally connected at its other end to a rod extendslaterally from the tank and is loosely connected by means of a or bar 40 which link 41 tothepiston rod 42 of a plunger 43 located .in a cylinder 44which is centrally supported in a receptacle 45 containing glycerin or asimilar substance. The receptacle 45 is supported by means of brackets 46 on and below the support or table 8 di- 8 or rather 25 in its lower portion a wing nut rectly under journaled'on and above the table or support a drum 47 which is transversely on brackets 48 extended upwardly from said table. That end of the rod or bar 40 to which the link41'is secured is also pivotally secured to a wrist pin 49 eccentrically located on one end of thedrum 47.

The cylinder 44 withinthe liquid container45 isprovide'd in its lower end with a port 50 which port has in its lower portion a valve seat 51 for a needle'va-lve 52 adjustably mounted in the lower end of the cylinder 44 and container 45 which valve is employed to regulate thequantity of glycerin or other suitableliquidpassing to and from the container 45 and the cylinder 44 through v the port 50 in said cylinder. 7 v The drum 47 carries a ratchet wheel 54 which rotates'therewith. Mounted on the table or support 8 near'zthe drum and preferably crosswise thereof is a bracket 55 to one of the uprights of which'bracket is pivotally secured a pawl 56 which is adapted to engage with itsfree end the teeth of the ratchet wheel '54. This pawl isnormally held out of engagement with the ratchet the spring 57 Connectingthe upper por-- tion of the cylinder 60 to thegasometer or tank 7 vis a pipe 63 which it will be ;observed islocated in the upper portion of said tank. Secured at one'of itsends to the drum 47 and woundthereon is aicable 64 which passes V over blocks 65 suitably supported overhead" and carries at its other end a weight 66 which is also connected to the cable by 'meanslo'f a'block 67 around which as'well as one of the blocks 65 the cable-can be riven as many times asdesired.

' Located at any suitable distance from-the tank 7 is 'an extension tank .68 which has upper portion .of the gasometer or generating tank as is clearly shown in Figs l and 3 of the (drawings The pipe 69. is provided with a valve 70 to control or'shut as the flow of gas from'the generating tank to the extensiontank; "The latter'tank has communicating there-with one end of a service pipe 71 which may. lead to any desired .point and to which a'weldin g tool may be connected in the well known way, or if desired,

said service'pipe can be suitably connected to light fixtures.

communication througha pipe 69 1witli'the From the foregoing and by reference to the drawings it will be readily understood and clearly seen that, assuming that the carbid receptacle is filled or supplied with carbid and that the closures 13 as well as the valve 70 are closed, and it is desired to start the operation of the apparatus, it is only necessary to cause enough carbid to be discharged from the receptacle 19 into the water 36 contained in the tank 7 to generate a sufficient amount of gas to fill the gasometer or tank 7 from which it can be transferred through the pipe 69 to the extension tank 7 by opening the valve 70 in the last named pipe. As the drum 47 is rotated by means of the weight 66 and cable 64 it is apparent that the rod or bar will be reciprocated and through its connections with the feeding slide 29, the latter will be moved back and forth in which operation lumps 72 of carbon will be forced oif the floor 24 of the extension 22 into the water. This operation will continue until the pressure within the tank 7 rises to such an extent as to cause the plunger 61 in the cylinder 60 to be depressed, which operation will cause the pawl 56 to engage the ratchet wheel 54 on the drum and to stop its movement until the pressure Within the tank 7 has been diminished by usage to such an extent as to permit the pawl 56 to be disengaged from the ratchet wheel 54, when it is obvious that the weighted cable will again set-the drum in motion.

In order to regulate the movement of the drum, the plunger 43 in the cylinder 44 with its connections with the drum is employed, for it will be observed that the movement of the plunger 43 can be regulated by adjusting the valve 52 so as to increase or diminish the size of the port 53 in the cylinder 44 so as to permit the glycerin to pass to and from the cylinder 44 freely or very slowly.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is- 1. In an apparatus of the class described, the combination with a generating tank adapted to hold water in its lower portion and having an inlet and an outlet therefor, of a carbid receptacle mounted within the upper portion of said tank and having an outlet in its lower portion, a feeding slide mounted below said outlet, a rotary drum located near said tank, connections uniting the feeding slide and drum and eccentrically connected to the latter, means to rotate the drum, and means eccentrically connected to the drum to regulate the speed of the movement thereof, said last named means including a valved cylinder and a plunger therein operable by said drum.
